To all whom it may concern lie it known that I. MlcIInLn N. SALvA'rI subject of the King of Italy, and resident oii Turin, Italy, have invented certain new and useful Improved Methods for Producing Metallic Alloys Containing Nickel of which the following is a specification.

In the art are known the drawbacks due to the presence of nickel in metal alloys because of its property of strongly oxidizing the melted metals and of giving rise to a large amount of uses.

This characterlstic of the nickel is particularly troublesome in cases where the use of the nickel is necessary for obtaining high resistances owing to the high cost of these alloys and to the fact that in many instances the ingots cast from said metals or alloys cannot be utilized being non-homogeneous and containing blisters of any kind.

On the contrary by the method according to this invention metallic alloys of any kind containing the required amount or percentage of nickel may be obtained in an easy manner, said alloys being free from the drawbacks above stated.

According to this invention nickel in stead of being mixed directly and by itself, that is in a practically ure condition; with one or more of the meta s with which it is to be alloyed, is added in the form of an alloy with zinc, to the other metal or metals of the desired final alloy.

It has beenfound that the resulting alloys in which nickel has been incorporated in the condition of an alloy with zinc, have Specification of Letters Patent.

the well known technical characteristics and particularly the high resistance due to the presence of nickel and further they are completely free from blisters or other defects referred to.

It has been ascertained by tests that it is advisable to alloy the nickel with the zinc by melting the nickel into the zinc as in this manner the association is effected in very good conditions; on the contrary by using an alloy obtained by melting zinc into nickel the resulting alloys have less marked properties, these resulting alloys being in any case better than those obtained by the methods now used in the art.

\Vhat I claim as my invention and desire to secure by United States Letters Patent is:

1. A method of manufacturing allo s con taining nickel and zinc, consisting in rst alloying together practically pure nickel and zinc and then adding the alloy thus obtained to the rest of the constituents of the final alloy.

2. A method of manufacturing alloys containing nickel and zinc, consisting in first alloying together nickel and Zinc by meltin the practically pure nickel into zinc and then adding the alloy thus obtained to the rest of the constituents of the final alloy.
